Abstract (in english)
   In addition to the natural gravitational slope movements, the occurrence of seismo-gravitational movements at Krušné hory Mts cannot be neglected in the region where earthquakes with maximum intensity of 7° are expected. Both phenomena raise potential danger to open-pit mines situated nearby foots of some risk slopes. Three factors for determination of seismic risk are necessary to know: (i) Price of machinery as well as the secondary losses caused by sliding masses should be completely estimated by the mine holder. (ii) Ground particle acceleration 0.1-0.2 g and moving masses up to a million cubic metres should be taken into account according to the published values for the joint estimation of vulnerability. (iii) Seismic hazard based on the local macroseismic observation and calculated for a 100 years interval amount to 0.6-0.8 at the seismic intensity 6° and 0.2-0.4 at the intensity level 7°
